9 ADU Plans to Choose from:

MINI UNIT PLANS 250 Sqft to 399 Sqft

The Mini’s are our most popular home sizes right now for good reason. They are small enough to fit on smaller inner city lots and their size makes them affordable to a much larger group of people. Don’t let their size fool you, these plans all feel much larger then they appear!
